Researching Wloszcz, Kontkiewicz, Stankiewicz, Nowosad

I have just recently begun to research my family tree and have come across these names. Wloszcz and Kontkiewicz from Poland. A Tomasz Kontkiewicz married Marjanna Wloszcz and had at least one female child Agata Kontkiewicz(1888-1948). Agata immigrated to the USA prior to 1914 from Poland. Any information on any of these people would be greatly appreciated. Thanks in advance.
